Renal transplant

Learning objectives

• Definition of a renal transplant
• Management of a living donor during a nephrectomy
• Management of a renal transplant recipient

Definition and mechanisms

• A renal transplant is the organ transplant of a kidney into a patient with end-stage kidney disease (ESRD)
• Classified as deceased-donor (formerly known as cadaveric) or living-donor nephrectomy (LDN)
• Improves both length and quality of life for patients with end-stage renal disease (ESRD)
• ESRD is defined as chronic kidney disease (CKD) with a glomerular filtration rate (GFR) <15 mL/min/1.73 m² or where renal replacement therapy is needed
• Diabetes is the most common cause of ESRD followed by glomerulonephritis, polycystic kidney disease, pyelonephritis, hypertension, and auto-immune disorders
• Two-year graft survival is > 80% for cadaveric and 90% for living-donor grafts and overall patient survival is > 95%

Signs and symptoms

See chronic kidney disease

Complications

• Bleeding
• Vascular thrombosis and stenosis
• Transplant rejection (hyperacute, acute, or chronic)
• Ureteral obstruction
• Urinary leakage
• Infections and sepsis due to immunosuppression
• Post-transplant lymphoproliferative disorder
• Electrolyte imbalance (particularly calcium and phosphate)
• Proteinuria
• Hypertension

Management of the living donor during nephrectomy 

Postoperative care of the living donor

• Provide postoperative analgesia via a fentanyl PCA
• Consider a paravertebral or TAP block to complement analgesia
• Avoid NSAIDs
• Apply early mobilization along with breathing exercises and incentive spirometry
• Consider postoperative complications:
  • Pulmonary embolism
  • Hepatitis
  • Myocardial infarction
  • Arrhythmias
  • Pneumonia
  • Atelectasis
  • Urinary tract infection
  • Wound infections
  • Splenic lacerations
